I'm lesbian ,why am I having thoughts about guys?

Hey guys so I have been suffering with sexual ocd due to the fact that I don’t feel that romantic spark with him anymore, I love him and I know I do but I get to much in my thoughts thinking about why can’t I feel that anymore what has changed what if I don’t wanna be with anymore I’ve been with him for 4 years and at first I think it was ROCD but now I started thinking what if I’m into girls now I’ve always been the type to say oh a girl is so pretty or I like this about her but now I feel like every time I see a girl I’m like do I see myself in a relationship with her oh she’s pretty oh I like her voice do I find it attractive and sometimes I do !!! Which is killing me I feel disgust thinking about because what if I secretly am no shame to people who are my sister herself is but I just feel wierd because I wanna be with my husband and feel happy there not with a girl and feel like a man because I see myself in the mirrior and I’m like do I myself being a man do I look lesbian? Do I act lesbian or bi? What if secretly I wanna be a man or I imagine myself being a man in a relationship with a pretty girl and idk what to think

Hi everyone I'm 18 and recently discovered i have soocd. I remember having random thoughts about men and it would make me feel uncomfortable and have bad panic attacks. Sometimes I would have to leave class bc these thoughts was messing with my head. And sometimes I would avoid men bc of this. I remember having a sex dream about one of my guy classmate and when ever I seen him I would have hatred for him. These thoughts keep on repeating over and over in my head to the point where I don't reaction to it. I don't if I'm slowly realizing im actually into men, but I still have this weird gut feeling in my stomach when I think about it. I really don't wanna lose my identity as lesbian.

I have a lot of trouble with my sexuality. I’ve been trying to figure out my sexuality for years. I’ve dated a man, and I wasn’t really into the whole time. And since then I’ve thought that maybe I’m a lesbian because I’m attracted to women, which I know for sure. But then my brain spirals, I constantly think back ti memories with my ex, how I felt with him, I check how it makes me feel. I often google to see if other lesbians have felt similar, I ask ChatGpt over and over again. I feel like I have to be 100% certain or that im faking for attention, or thst I’ll end up with a man. I guess im wondering has anyone else felt like this ? What’s been your experience how do you manage it?
